o iginal application filed February 17, 1920, Serial No. 359,435. Divided and this application filed March 22, 1920. Serial No. 367,973.

T 0 all whom it may concern:

Be it known that I, ARON M. BEAM, a citizen of the United States of America, re-

iding at the city and county of Denver and State of Colorado, have invented a new and useful Power-Transmitting Reciprocatlve- Movement Mechanism, of which the following is a specification. I

My invention relates to anew and 1mproved type of power transmitting reciprocative movement mechanism, and the objects of my invention are:

First. To provide a thoroughly practical and easily operating reciprocating mechanism having power enough to operate several different and independent reciprocating mechanisms simultaneously.

Second. To provide a geared form of power transmitting reciprocal movement actuating mechanism that can be arranged in units of one, two or more mechanisms, that can all be operated simultaneously from one source of rotative power.

Third. To provide an easily constructed, simple and powerful reciprocative movement mechanism that is inexpensive to manufacture and is easily and quickly ap plied to retort furnaces for roasting ore and oil shales that have a number of retorts with ore rabbling and scraper mechanisms in them, and that can also be applled to multiple deck ore driers and to other machines that use mechanisms that move reciprocally.

I attain these objects by the mechanism illustrated in the accompanying drawlngs, in which:

Figure 1 is aside elevation of the improved power transmitting reciprocating movement mechanism.

Fig. 2 is a front view thereof.

Fig. 3 is a side elevation of a series of the mechanism shown in Fig. 1, and connected to operate in unison; and

Fig. 4 is a horizontal the line H of Fig. 1.

Similar letters of reference refer to $11111- lar parts throughoutthe several views Referring to the drawings:

The numeral 1 designates the frame work of a reciprocating mechanism embodying my invention. In this new, the numeral 2, designates the back plate, and the numerals sectional view on 3 and 4, designate cast brackets that form the lower and upper ends of the frame, and

at the inner and outer ends of these brackets, I place vertical castiron standards 5 and 6, that are secured to the brackets at their up per and lower ends, thus formingv a stationary square shaped supporting frame having a large clear space through it between its side and end members, for the moving parts of my power transmitting, reciprocating mechanism, the weight of which may be supported on any suitable support, such as a brick pier 6 7 The upper and lower brackets and themner vertical standard are securely bolted to the back plate 2, which member is used to secure the reciprocating mechanism to a machine of any kind where it is desired to use a reciprocating movement, to drive reciprocally any part of it. This back plate can be dispensed with if it is not needed.

The opposite ends of the upper and lower brackets are provided with depending lugs 7 and 8, that extend into the recesses .9 and 10, that are formed by the opposing side standards 5 and 6, to. receive them. These lugs are provided with apertures through w iich rods 11 and 12, are slidably mounted. To these rods I secure the upper ends of a reciprocating frame 13, that is positioned in a vertical plane between the upper and lower brackets. These rods are secured to the opposite ends of the frame 13, prefer: ably by extending the rods through long lugs 1% that are formed at its opposite ends, and securing them in any desired adjusted position by set screws 15. Consequently, these upper and lower rods are slidably secured in the lugs 7 and 8, of the brackets, and-are rigidly secured in adjusted positions to the vertical frame, and when this frame 13, is reciprooated, the rods reciprocate with it.

To the center of the height of this reciprocating frame, a third rod 16, is secured to a hub 17, that is formed on the adjacent side of the reciprocating frame and it, as well as the upper and lower rods, extends through apertures 18, that are formed through the back plate 2, and they can also be further supported by additional bearing devices on the machine to which my reciprocal movement is applied, and if desired, they can be slidably supported in sleeves 19, as shown in my pending application for a patent for a multiple retort ore and oil shale roasting the ore roasting furnace of that application.

While I have shown three rods in my present application being attached to and consequently reciprocated by the reciprocat- "ing frame, I desire it understood that the center rod can be dispensed with if desired, or that one or two or more rods can be attached to any predetermined part of the height of the reciprocating frame. The up- -per and the lower rods are essential to the support of the reciprocal frame which is mounted on them, but they can be used just the same for imparting a reciprocal movement to any machine part or combination "of parts to which they may be attached, that 7 requires such a movement, as in the furnace application above referred to, but there may be machines that will require one or two or more rods positioned at and extending from different points of the vertical height of the reciprocating frame than I have shown in V the drawings'of this application.

This vertically positioned reciprocating frame 13, comprises 'a casting, and 1t contains a vertically arranged slot 20, the opposite sides of which are machined to receive slidably a cross-head21, that is made in two equal halveswhich are bolted together by bolts 22.

This cross head contains a central aperturethat is bored to fit on the crank pin 23, of a crankshaft 24, that is journaled in bearings 25, that are secured upon brackets 25*, that are bolted to the opposing sides of the standards 5 and 6. This crank shaft" I extends beyond the bearings 25, and on one of its ends a gear wheel 26, is secured. This gear wheel meshes with a gear pinion 27, that is secured to one end of a counter shaft 28, that is journaled in bearings 29, that are secured to brackets 30, that are formed on' the outside faces of the outer standards 6, and'a belt pulley 31, or if preferred, a sprocket wheel, is secured on the opposite end of this countershaft and can becons nected to any suitable source of rotative power by which the countershaft can be rotated to cause its gear pinion to rotate the gear wheel on the crank shaft, and consequently the crankshaft, which causes the crank pin of the crank shaft to reciprocate the cross head in the vertical slideway in the reciprocating frame 13, and this action will reciprocate the vertical frame 13, and

- the upper and lower rods 11 and 12, in the lugs of the brackets, and also the central rod 16, all three rods moving in the same reciprocal direction, and all at the same time, and

the reciprocal frame moves reciprocally between the four vertical side standards 5 and 6. 1

If desired, two or three or more of these power reciprocating mechanisms can be arranged one above the other, as shown in outline in Fig. 3, in which they can be driven from the pinion shaft of one of the reciprocating mechanisms by connecting the pinion shafts of the other two mechanisms by sprocket wheels 32, and chains 33, as shown in this figure, in which case the rotative power receiving pulley 31, can be applied to the pinion shaft of either one of the two or three or more reciprocating mechanisms.

When two or more of my reciprocating movement mechanisms are used one above the other, a supporting block 34, is placed between them and is secured to them and to the back plate 2.

My invention provides a simple and powerful reciprocating mechanism, and while I have illustrated the preferred construction of its essential features, I do not wish to be limited to it, as changes can be made without departing from the spirit of m invention.
